2 bytes of memory because the pointer variable, whatever data type it maybe pointing to is always an unsigned integer as the address is always a positive integer, hence requiring 2 bytes of memory

Pointer is actually is a reference to memory cell. In 32bit operating system, OS use 4 byte for pointing to any memory cell thats why only 4GB memory can be used in 32bit operating system. On the othe...

Ans :: 50Because at the end the value of x changes to 50 so 50 will be the result.

The ans is 50 irrespective of the initial value of x bcos at the end of the code we are overwriting the variable x with 50.
What does the following function print?func(int i){if(i%2)return 0;eale return 1;}main(){int =3;i=func(i);i=func(i);printf("%d",i);}a.3b.1c.0d.2

The answer is 1 because where i%2 it gives 1 then if condition is true and it returns 0 to the main, again we call the function then if condition fails and then else part execute so answer is 1.

Ans :: C Because :: func(3) >>> return(1) >> i=1; func(1) >>> return(0) (because i is int type) >> i = 0 will be printed.
